题目：建立一个简单的TCP客户端和服务器.

1.采用socket模块建立

Tcp服务器代码:

#!/usr/bin/env python
# -*- coding:utf-8 -*-
# create Ttstcy
from socket import *
from time import ctime
'''
一个简单的tcp服务器

'''
Host='127.0.0.1'   
Port=56478
Buffer=1024
add=(Host,Port)

tcpSocket=socket(AF_INET,SOCK_STREAM) #建立socket套接字
tcpSocket.bind(add)                   #绑定地址
tcpSocket.listen(5)                   #接受最大连接数

while True:
	print('waiting for connection......')
	tcpSocket,add=tcpSocket.accept()       #接收客户端连接
	print('connection from:' , add)

	while True:
		data=tcpSocket.recv(Buffer)
		if not data:
			break;
		tcpSocket.send('[%s] %s' % (ctime(),data))  #返回消息

	tcpClient.close()            #关闭当前客户端连接
tcpSocket.close()

Tcp客户端代码:

#!/usr/bin/env python
# -*- coding=utf-8 -*-
# create Ttstcy

from socket import *

'''
一个简单的TCP客户端

'''
Host='127.0.0.1'
Port=56478
Buffer=1024
Add=(Host,Port)

tcpClient=socket(AF_INET,SOCK_STREAM) #建立socket套接字
tcpClient.connect(Add)                #连接服务器

while True:
	data= raw_input('> ')
	if not data:
		break;
	tcpClient.send(data)            #向服务器发送数据
	data=tcpClient.recv(Buffer)
	if not data:
		break;
	print data

tcpClient.close()                 #关闭客户端连接

2.采用SocketServer创建

Tcp服务器代码:

#!/usr/bin/env python
# -*- coding=utf-8 -*-

from SocketServer import *
from time import ctime

'''
简单的SocketServer Tcp服务器

'''

Host='127.0.0.1'
Port=15489
Add=(Host,Port)

class MyRequestHandler(StreamRequestHandler): #重写Handler方法
	def handler(self):
		print 'connection from :',self.client_address
		self.wfile('[%s] %s' % (ctime(),self.rfile.readline()))  #wfile来发送data，readline()用来获取客户端date

tcpServ = TCPServer(Add,MyRequestHandler)     
print 'waiting for connection...'
tcpServ.serve_forever()  #无线循环请求

TCP客户端:

#!/usr/bin/env python
# -*- coding=utf-8 -*-

from socket import *

'''
SocketServer 客户端

'''
Host='127.0.0.1'
Port=15489
Buffer=1024
Add=(Host,Port)

while True:
	tcpClient = socket(AF_INET,SOCK_STREAM)
	tcpClient.connect(Add)
	data= raw_input('>')
	if not data:
		break
	tcpClient.send('%s\n' % data)
	data= tcpClient.recv(Buffer)
	if not data:
		break
	print data
	tcpClient.close()
